Fig. 5 is a view similar to Fig. 4 showing the parts in altered position.

The bread toaster disclosed herein consists of a case A in which is disposed a framework B. This framework includes two spaced end frame members. A number of heating elements disposed within the framework B form two spaced bread ovens C and provides a space therebetween. In the bread ovens C are disposed two vertical'movable bread racks D which support the bread and which are spring biased to non-toasting position. These bread racks extend through one of said end frame members and are connected together exteriorly thereof through suitable attaching means. For operating the bread racks, operating mechanism E is employed which consists of two parallel levers pivoted at one end of each lever to said attaching means and pivoted at the other end of each lever to one of said end frame members. These levers cause parallel movement of the bread racks D within the bread ovens C. Below the said parallel levers are provided two crossed operating levers, one operating lever being pivoted to one end frame member and the other operating lever being pivoted to the other frame member. A sliding connection between these operating levers causes downward movement of one lever upon corresponding movement of the other lever. A link extending between one of said crossed operating levers and one of said parallel levers serves to cause downward movement of the bread racks upon downward movement of either of said operating levers. The pivot for said link to said parallel lever is situated intermediate the center of said lever and its pivot to the frame. The pivot for said link to said operating lever is situated between said sliding 'connection and the free end of said lever whereby multiplication of movement is procured causing greater movement of the bread racks than the free ends of the operating levers. Actuation of the toaster is procured through a timing device F. This timing device controls a switch mechanism G by means of which the heating elements are energized. A color control device H operable from either end of the toaster serves to regulate the color of the toast. These various parts will now be described in detail.

The case A of the invention, shown in detail in Figs. 1, 2 and 4, consists of a lower case section It! and an upper case section H. Case section I!) has sides l2 and I3 and which have formed on them inwardly turned end portions [4 and !5 best shown in Fig. 1. The sides l2 and I3 and end portions 14 and I5 are formed with an offset |6 which provides a recess I! extending about the uppermost portion of said case section. A bar I8 is secured to the offsets l6 of the end portions I4 and tie the parts of the lower case section together. This bar may be welded, brazed, or otherwise secured to the said offset whereby the parts are securely held attached to one another. The upper case section II is dome-shaped in form having sides l9, ends as and a top 2|. The lower marginal portions 22 of the upper section II is received in the recess IT. For holding the parts together the marginal portion 22 of the ends are formed with inwardly turned lips 23 which are adapted to snap under the bars I8. The bars l8 are arranged in inclined relation so that when the upper case section is forced downward the lips 23 are sprung apart. When the said lips pass beneath the lower edges of the bars IS the said lips again spring in position and hold the parts assembled.

For closing the ends of the lower case section l6, end pieces 24 are employed which are constructed from a plastic material. The lowermost portion of the sides |2 and I3 and the end por tions l4 and I5 are turned inwardly as indicated at 26. These portions of the case section have upwardly extending flanges 21 which terminate in a number of horizontally disposed cars 28. The end pieces 24 are formed with feet 25 which underlie the ears 28 of the side l2 and I3. Screws 29 extend through these feet and are screwed into said ears. Other screws 30 extend through a clip 3| and are screwed into the end pieces 24.

These clips engage the bars I8 and hold the uppermost portions of the end pieces attached to the case proper.

The framework B includes a frame 32 of inverted U-shape having end frame members 33 and 34 and an upper frame member 35 connected therewith. The frame members 33 and 34 have flanges 36 which overlie certain of the cars 28. Screws 3'! pass through these cars and are screwed into the flanges 36 and serve to attach the lowermost portion of the frame to the case proper. 32 has openings 38 formed therein which communicate with the bread ovens C. These openings communicate with other openings 39 in the top 2| of the upper case section II. Depending flanges 49 formed on the top 2| of case section extend downwardly into and are received in similar flanges 4| formed at the upper frame member 35 of frame B. For the purpose of centering the case A with respect to the frame 32 at the locality of the joint between the two frame sections, projections 42 are formed in the end frame members 33 and 34 and which are adapted to engage the offset l6 formed on the lower case section I0 as best shown in Fig. 4.

The lowermost portion of the toaster is closed by means of a bottom 43. This bottom consists of two end portions 44 and 45 and an intermediate closure 46. The closure 46 is hingedly connected to the end portion 44 through a hinge 41 and is detachably secured to the end portion 45 by means of a spring clip 48. This closure is provided with openings 49 which give the desired amount of draft to the toaster. The end portions 44 and 45 are held attached to the case A by means of the screws 29 and 31 previously referred to.

The bread ovens C are formed by the end frame members 33 and 34 of frame 32 and by means of four heating elements 5|, 52, 53 and The upper frame member 35 of frame 54. These elements consist of sheets of mica on which are wound suitable resistors 56. The heating elements 52 and 53 are separated from one another to form a space 51 therebetween and in which portions of the mechanism E for operating the toaster is disposed.

The heating elements 5|, 52, 53 and 54 have reinforcing strips 58 secured to the same at the top and bottom thereof. These reinforcing strips have ears 59 projecting outwardly therefrom and into the bread ovens C. Guard wires 60 are attached to these ears and extend into the bread ovens C and hold the bread spaced from the heating elements to prevent burning of the bread.

Th heating elements of the invention are supported in the following manner: Extending beneath the heating elements at the ends thereof are two bars 6| and 62 which are constructed and supported in the same manner. Only the bar 62 has been shown in detail and will be described. This bar has upstanding flanges 63 at the ends of the same and which are threaded to receive screws 61. The screws 61 pass through the sheets of mica 55 and are screwed into the said flanges. Washers 64 disposed on each side of. the mica serve the usual purpose. In the center of the bar 62 is a channel-shaped support 65 which has flanges 66 similar to the flanges 33 extending upwardly therefrom. Screws 68 similar to the screws 61 extend through the sheets of mica of the heating elements 52 and 53 and attach the same to the bar 62. The support 65 is attached to the bar 62 by means of a screw 59 which extends through said bar and is screwed into the support 65. The bars 62 have attached to them by means of screws 15, arms 1| which project through insulators 72, mounted in the end frame members 33 and 34. The upper ends of the heating elements 5|, 52, 53 and 54 are held in place by means of insulators 13 which are mounted in the upper frame member 35.

The bread racks D are used in supporting the bread within the bread ovens C and are both identical in construction. These bread racks are each constructed from a bar I4 of metal having lugs projecting outwardly therefrom, the alternating lugs extending in opposite directions. The said bars extend through slots 16 in the end frame members 33 and 34. For supporting the said bread racks the following construction is employed: Disposed exteriorly of the end frame member 34 is a yoke 11 of metal having two arms 18 and 79. These arms have slots in the same and which are angular in form. The ends 8| of the bars 14 project through these slots. These ends 8| have fingers 82 formed on the same and which are normally bent to correspond with the angularity of the slots 80. After the parts have been assembled the said fingers are straightened out as shown in Fig. 3 and the bread racks D become rigidly supported on the yoke TI.

The operating mechanism E of the invention includes two parallel levers 83 and 84. These levers are pivoted by means of rivets 90 to lugs 85 best shown in Fig. 4. These lugs are formed by striking the metal out of the end frame member 34 to leave openings 86 in said end frame member and through which the levers 33 and 84, extend. The other ends of said levers are pivoted by means of rivets 3| to lugs 81 formed on the yoke Ti. By means of this construction the two bread racks D are guided for up and down movement upon swinging of the levers 83 and 84 and during such movement maintained in horizontal position.

The operating mechanism E further includes two crossed operating levers 88 and 89. The lever 88 is pivoted by means of a rivet 92 to a lug 93 formed on the end frame member 34. The other lever 89 is pivoted by means of a rivet 94 to a lug 95 formed on the end frame member 33. The two levers 83 and 89 and the levers 83 and 83 travel in a vertical slot 96 formed in the end frame member 33 while the lever 89 travels in a slot 91 formed in the end frame member 34. The lever 88 has a slot 98 in the same extending longitudinally thereof and located at the portion of the same where the lever 89 crosses the lever 88. Attached to the lever 89 is a pintle 93 which is received in the slot 98. It will readily be comprehended that by means of this construction the two levers are caused to move in unison and upon depressing either of said levers the other lever moves with it and in the same direction. The lever 89 is: connected by means of a rivet IQI to a link I99. Link I09 is connected by means of a rivet I92 to the lever 94. It will be noted that the rivet I32 is disposed intermediate the center of the lever 84 and the pivot 90 while the rivet IilI is disposed intermediate the pintle 99 and the free end of the lever 39. By means of this construction a lever advantage is gained so that the levers 83 and 84 together with the bread racks D travel a greater distance than the levers 88 and 89.

The operating mechanism is urged to move the bread racks D into non-toasting position. This is accomplished by means of a tension coil spring I93 which is hooked into a hole I54 in the lever 98 and which is further hooked on a bracket m5 issuing outwardly from the end frame member 33. The said bracket has a hook I95 which is hooked into a hole I01 in the upper frame member 35 of frame 32.

The timing mechanism F of the invention is of the type disclosed in the patent to R. Sardeson 2,365,909 issued December 26, 1944. This timing mechanism includes a strip of bimetal I57 which is mounted for reciprocating movement in a guide I03. This guide is in the form of a bracket which is attached to an end plate I99 forming part of the framework B. The end plate I99 has a foot HE! which rests upon and is attached to the flange 36 of the frame member 35 by means of a screw II i. The upper end of said plate has an offset H2 which is formed with a flange H3 secured to the end frame member 39- by means of a screw H4. The strip of bimetal I01 is further supported on a swinging mounting H5 which is constructed from sheet metal and which has ears HIS extending upwardly therefrom. A stud H1 extends through these ears and is attached to the end plate I99. This stud supports the mounting H5 for swinging movement. The mounting H5 has a guide H9 through which the strip of bimetal I91 extends. By swinging the mounting IE5 the guide H3 can be raised and lowered to vary the elevation of one end of the strip of bimetal.

Attached to the end plate IE9 is a stud H9. Rotatably mounted on this stud is a plate I29 which has a hub I2! secured thereto and forming a. bearing through which the stud H9 extends. A nut 232 on the end of said stud holds the plate I25 in position. The plate I20 has attached to it a gear segment I22 which is formed with gear teeth I23. The teeth I23 are adapted to mesh with a rack I24 formed in the strip of bimetal I91 by means of openings I25. The segment I22 is attached to the plate I by means of rivets I25. The plate I20 is formed with anumber of ratchet teeth I21 which form a ratchet indicated by its entirety by the numeral I28. These teeth are adapted to engage a catch I29. Catch I29 is pivoted on a stud I30 which is secured to the end plate I99. The catch I29 has a finger I3I which rests upon the strip of bimetal I91. A tension coil spring I32 is secured to the catch I29 on a pin I33 mounted thereon and also to a part carried by the end plate I09. This spring maintains the finger I3I in contact with the strip of bimetal I91 and also the catch I29 in engagement with the teeth I21. Below the strip of bimetal is mounted a heater I34 which serves to heat the strip of bimetal. When the bimetal is heated the same bows upwardly and the finger I3I is raised to disengage the catch I29 from the engaged tooth of the teeth I21. This causes the gear segment I22 to move and to shift the bimetal along to present a new section of the bimetal to be heated. The same procedure then reoccurs and the ratchet segment I23 is released one tooth at a time.

The timing device further includes a U-shaped arm I35 which has spaced flanges I39 and I31. A stud H39 extends through these flanges and is secured to the end plate I99. A clip I39 secured to said stud holds the arm I35 in position. The arm I35 has pivoted to it a depending latch I49. This latch is disposed between the flanges I36 and I31 and is mounted on a pintle MI extending through said latch and flanges. The said latch has a catch I42 which is adapted to engage a catch engaging lever I43 pivotally mounted on a stud I39 secured to the end plate I09. The said lever has a shoulder Hi5 which engages the catch I22. The lever M3 has an arm I46 which is disposed oppositely to the shoulder I and which is adapted to engage an abutment I41 formed on a lever Hi3. Lever I49 is pivoted on a stud I43 which is secured to the end plate I09. The spring I32, previously referred to, is hooked on a hook I59 formed on the lever I48 and urges the abutment Hi1 into a position to be engaged by the arm I55. The plate I29 has a pin I5I secured thereto and which is adapted to engage the lever I 53 and to swing the same in opposition to the action of the spring I32 and in a direction to disengage the abutment I41 from the arm I43. The pin i5I is so positioned that when the strip of bimetal I9? reaches the end of its movement pin I5I engages lever I53.

The arm I35 is urged upwardly by means of a torsion spring I52. This spring has a coil I53, the ends of which are indicated at I54 and I55. The end I55 of the said spring has a loop I55 which is looped about the pintle MI. The other end I55 of the said spring is offset and extends through a hole i5? in an arm I58. Arm I58 is pivotally mounted on a rivet I59 which is secured to the plate I25. The other end of said arm has a slot I55 in the same and through which passes a pin I5! secured to the latch I99. This spring urges the arm E35 upwardly and the pressure on the said arm increases as the ratchet I28 approaches the end of its movement.

For the purpose of moving the arm I35 into its latching position as shown in Fig. 5 a link I52 is employed. This link has a hook I63 which extends through a hole ii in the lever 39. The upper end of said link has attached to it a stud I65 which has a shank I93 movable in a slot I61 formed in the latch I 49. This 510; bananashaped in form and the shank I69 is adapted to move from one end to the other of said slot.

For the purpose of determining the brownness of the toast the color device H is employed. This device consists of a screw I98 which is screwed in a tapped lug I99 formed on the end plate I99. The said screw is further guided for rotational movement in another lug I70 formed on said plate. The screw I68 has a screw-driver slot in its lower end III by means of which the same may be rotated. The upper end of the screw I68 extends through an arm I72 formed on the mounting H and has a head I86 which engages the upper surface of said arm. This arm extends through the end plate I99 and upon movement swings the said mounting to vary the engagement of the teeth I27 of ratchet I28 with the catch I29. The said screw has mounted on it an arm I 73. This arm is formed from resilient sheet metal and is threaded to receive the said screw. The said arm further has a spaced threaded portion I74 connected to it by a resilient connection I75. This connection provides friction between the threaded part of the arm and the threaded. portion I74 whereby friction is created between the arm and the screw and the arm caused to travel with the screw. The arm I 75 has pivoted to it by means of a rivet 79 a link I77. This link is in turn pivoted by means of a screw I78 to a lever I79. Lever I79 is disposed below the frame 32 and underlies the flanges 36. This lever is pivoted to a cross bar I89 by means of a screw I8I. Cross bar I99 is secured to the flanges 27 by means of screws I82 as best shown in Fig. 1. The lever I79 extends through slots I83 in the end pieces 29 and projects outwardly beyond the same. To the extreme ends of this lever are attached knobs I84. The slots I89 have lateral extent and the lever I79 may be swung laterally about the pivot formed by the screw I8I from one side of the toaster to the other. This causes the arm I73 to be rotated a portion of revolution upon the swinging of the lever I79. Said lever raises and lowers the mounting II5 thus varying the degree of engagement of the catch I29 with the teeth I27 and consequently the brownness of the toast.

For operating the levers 88 and 89 two extensions I 37 and I89 are employed. These extensions being identical in construction only the extension I87 will be described in detail. This extension consists of a body I99 which overlies the outermost end of lever 88. This body has a flange I99 extending at right angles to the body and formed with a hole not shown in the drawings and through which the lever 89 extends. The said body has a finger I9I which extends through a vertical slot I92 in the outermost end of said lever. A looped wire spring I99 extends about the flange I90 and is hooked under the lever 89 and also under the body I87. This spring urges the fingers I9I to the upper end of the slot I92. The body I87 has a bar I94 issuing therefrom and which extends through a vertical slot I95 in the end piece 24. Mounted on the end of the bar I94 is a knob I97. A set screw I96 holds the said knob attached to the bar. The purpose of the extension I77 is to compensate for various irregularities in the manufacture of the toaster. In a similar manner a knob I99 is attached to the extension I88 and which is mounted on the lever 99.

The switch mechanism G of the invention is best shown in Figs. 2 and 3. This switch mechanism includes a support I99 which is stamped from sheet metal and which has legs 20!] projecting outwardly therefrom. These legs are attached to the end frame member 33 and hold the support I99 spaced from said end frame member. The lowermost part of this support I99 has flanges 29I projecting outwardly therefrom and which have attached to them a bar 292 of insulating material. Rivets 293 extend through these parts and hold the same attached. This bar of insulating material carries two fixed contacts 294 and 295 which are mounted on screws 296 and 297 which are secured to said bar. These contacts are connected in the circuit with the heating elements SI, 52, 53 and 59 in the usual manner. Pivoted to the support I99 is a lever 298 constructed of insulating material. This lever is mounted on a stud 299 secured to the support I99. A clip 2I9 attached to the end of this stud holds the said lever in position thereon. The lever 299 has an arm 2 I I which has pivoted to it by means of a rivet 2I2 a swinging contact bar 2I3. This bar has ears 2M extending upwardly therefrom and through which the rivet 2I2 extends. The said contact bar is also formed with movable contacts 2I5 which when the lever 298 is swung in a clockwise direction engage the contacts 294 and 295 and closes the circuit through the same. The lever 298 has at its other'end an arm 2 I9 which is formed with a slot 2I7. In this slot is received one end of compression coil spring 2I8, the other end of which encircles 2. lug 2I9 formed on a lever 229. Lever 220 is pivoted to the support I99 by means of a rivet 22I. A link 223 is pivoted on a stud 222 which is secured to the end of the lever 22!). This link has a headed end 224 which extends through the slot I94 in the lever 38 and in which the spring I03 is hooked. By means of this construction the arm 229 is connected to the lever 88. As the lever 88 descends lever 229 is moved downwardly and the spring 2I8 compressed. When the spring passes dead center with respect to the end of the slot 2I7 and the rivet 2I2 spring 2I8 moves over center and snaps contact bar 2I3 downwardly causing the contacts 2I5 to close the circuit through the contacts 295. The reverse occurs when the link 223 is moved upwardly. A clip 225 secured to the end of the stud 222 holds the link 223 mounted on said stud.

To retard the movement of the bread racks D to non-toasting position a dash pot 226 is employed. This dash pot is mounted on a bracket 227 issuing outwardly from the end plate I09. This dash pot has a piston 228 and to which is pivotally connected a connecting rod 229. This connecting rod is pivoted to a stud 239 secured to the plate I29. When the plate I29 is moved to normal position in the resetting of the toaster piston 228 is forced inwardly into the dash pot 226 and air leaking by the piston of the same retards the movement of the parts.

The operation of the invention is as follows: Normally the parts are arranged as shown in Figs. 1, 2, 3 and 4. Upon exerting pressure on either of the knobs I97 or I99 the corresponding lever 98 or 89 is moved downwardly. Due to the pintle 99 operating in the slot 98 both levers 88 and 99 are caused to simultaneously move downwardly. Lever 89 being connected to the arm I 35 by means of link I52 and latch I99 the said arm is caused to swing downwardly with downward movement of said levers. The stud I on link I62 being in the lefthand end of the slot I67 as shown in Fig. 4 urges the latch I49 toward the 9 right. As the latch descends said latch strikes the catch engaging lever I43 and moves the same downwardly. This causes the arm I46 to move upwardly and to shift the abutment I4! to the right as viewed in Fig. 4. Due to the spring E32 the said abutment yields to permit the arm I56 to engage the end of said abutment as shown in Fig. 5. When the latch Hill nears its lowermost position the catch I42 drops below the shoulder I45 of lever I43 and latches the lever I35 in the position shown in Fig. At the same time lever 88 moves downwardly, the spring 2 I 8 passes dead center and snaps the contact bar 2 I3 downwardly to close the circuit through the contacts 284 and 295. This energizes the heating elements 5|, 52, 53 and 54 as well as the heater ltd. The heater I34 now commences to bow the strip of bimetal I01 and when the finger I3I is sufficiently raised, catch I29 becomes disengaged from the first tooth of the teeth I21 of ratchet I28. Plate I29 now rotates in a counterclockwise direction slowly dragging with it the arm I58 and the connecting rod 229. As the heater 34 continues to function plate I28 is given a step by step movement until the pin IEI reaches the lever U38. This pin then swings the said lever in a clockwise direction and disengages the abutment it"! from engagement with the arm I 36. This releases the latch Hill and spring I83 now moves lever 88 and through the levers 33, 8t and 83 and the link I06 the bread racks D upwardly. This resets the toaster to nontoasting position. When the plate I was at its opposite position to that illustrated in Fig. 5 just prior to release of the bread racks the arm I58 was in a downward position and pin ISI in the 1 upper end of the slot I60 of said arm. Movement of the arm !35 upwardly moves arm I58 upwardly and the plate I2!) is reset to the position shown in Fig. i. If it is desired to manually release the toaster the same can be accomplished by pushing either of the levers 88 or 89 downwardly when in their position shown in Fig. 5. Normally when the levers are moved into toasting position stud I65 is in the lefthand end of the slot I61. When, however, the levers 83 or 89 are released stud I6=5 travels to the upper or righthand end of the slot I61 and occupies the position shown in Fig. 5. If one of the levers 88 or 89 is now depressed the stud I65 engages the latch It!) at the righthand end of the slot which has the effect of moving the catch Hi2 out of engagement with the shoulder M5. This releases the toaster and the parts are immediately moved into non-toasting position.

The advantages of the invention are manifest. The toaster is entirely automatic. The energizing of the toaster mechanism and the control of the color may be operated from either end of the toaster. With the operating mechanism utilized, the bread racks are rigidly supported. The lever system used for supporting the bread racks maintains the bread racks in horizontal position during their movement toward and from toasting position. With the crossed operating levers employed straight strips of metal may be utilized in the production of the same and economy in fabrication of the levers results. With the extensions on the ends of the operating levers, inaccuracies in the construction of the toaster are compensated for and the operating knobs brought up to normal position regardless of the positions of the operating levers. With the particular invention disclosed multiplication of movement of the bread racks is secured whereby limited downward movement of the operating 10 knobs procures sufficient movement of the bread racks to bring them well within the bread ovens.

Changes in the specific form of the invention, as herein described, may be made within the scope of what is claimed without departin from the spirit of the invention.

Having described the invention, what is claimed as new and desired to be protected by Letters Patent is:
